VACUUM CLEANER.

v Application filed July 26, 1922'. Serial No. 577,645..

The object of the invention is to provide a motor actuated vacuum suitable particularly for use in removing dust from clothing, tapestries, fabrics and the like and designed with a view to facilitate the manual direction and positioning thereof with reference to the surfaces to be cleaned and of effecting the detachment and removal of accumulations of dust with the minimum risk of injuryto the fabric or pile regardless of the relative delicacy thereof; and further to provide a device for the purpose indicated which in matters of construction and the assemblage of parts is simplified tothe utmost extent with due consideration for facility of operation and removal of the 001 lection of dust made in the course of the operation of th mechanism; and with these objects in view, the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawing, wherein;

Figure 1 is a longitudinal sectional view of the cleaner.

Figure 2 is a section onthe line 3--3 of Figure 1.

The casing of the apparatus embodies essentially a nozzle and a handle 11 of which the latter is connected with the former by means of a threaded joint 12'and of which the latter constitutes a receptacle for a dust container or bag 13, removably fitted therein and displaceable therefrom upon the removal of the cap 14 fitted upon the rear end thereof and preferably engageable there with by a screw oint 15.

The nozzle preferably consists of aonev piece casting of suitable, preferably light, metal such as aluminum having a fan chamber 16 communicating by means of an opening 17 with a forwardly directed conveyor 18 which communicates at its front end with a brush chamber 19 having an open face which is fitted with a removable guard 20 adapted to be sprung or she ped into place for facility in removal and iaving an outwardly convexed or arcuate form as indicated clearly in Figures 1 and 2, the chord of the are being parallel with the length of the implement.

Attached to the upper side or back of the casting forming the nozzle, and in registration with an opening formed therein, is

the cylindrical wall 31 of a motor casing,

' secured in place, for example, by screws 32 and fitted with. a r movable domed. cap 33 having a suitable connection 34: with said wall, and fitted upon the motor shaft 35 which extends downward into the fan chamber 16 ,is a sleeve hub 36 carrying a fan 37 and provided at its lower end with a pulley 38 connected by a belt 39 with a similar pulley 40 on the core of the brush. The lower wall of the conveyor 18 is also preferably provided with an opening 41 fitted with a removable cap 12 adapted to be sprung into place and hence removable to give access to the pulley 38 and provide for the proper engagement of the belt therewith. The guard 20 which has its edges against the walls of the dust receiving opening, is yieldingly held against displacement by the tensile action of the driving belt 39, which serves to connect the pulley 40 of the brush with the pulley 38 at the lower end of the fan hub 36.

p The side walls of the handle member of the casing are provided with slots 43 form ing vents for the relief of air pressure in the apparatus due to the action of the suction fan, while the dust receptacle or bag 13 which is open at both ends and is designed for the reception of the dust drawn into the nozzle are connected by means of the longitudinally extending transversely spaced webs 51 and the resultant slots in said sleeve registering with corresponding slots in the handle to permit the outlet of air.. Obviously the bag or receptacle may be readily removed for thorough cleansing, simply by the contraction of the retaining sleeve, and such removal is facilitated by 'the fact that the handle member of the casing is preferably enlarged toward its rear end and the bag or receptacle is correspondingly tapered as will be obvious by reference to Figure 1.

What is claimed is. I

1. A vacuum cleaner having hollow nozzle and handle members of which the former carries a suction producing means comprising a fan and a fan chamber, saidhandle member being in communication with the fan chamber and providedwith longitudi nally extending air vents, and an elongated air penetrable dust bag removably fitted in the handle member and provided with terminal expansion rings, said-handle member having a removable closure at its outer end.

2. A vaeuum'clean'er having hollow nozzle and handle members of which the former carries asuction producing means comprising a fan and a fan chamber, said handle member forming a dust receiving chamber in communicationwith the fan'chamber and being expanded toward its rear end. and an air permeable dust bag removably fitted in the handle and carrying expansible retaining means for engagement with the walls thereof, said handle member having a removable closure at its outer end.

3. A vacuum cleaner having hollow nozzle andhandle members of which the former carries a. suction producing means comprising a fan and a fan chamber, said handle member being in communication with the fan'chamber and provided with longitudinally extending air vents, and a removable, air penetrable, dust receiving and holding bag fitted within the handle member and containing expansible retaining means, said handle member having a removable closure at its outer end.

4. A vacuum cleaner having'hollow nozzle and handle members of which the former carries a suction producing'means comprising a fan and a fan chamber, said handle member being in communication with the fan chamber and provided with air vents, and an air penetrable dust bag removably fitted within the handle member and carrying an expansible retaining sleeve provided with air vents registering with those in the handle member, said handle member having a removable closure at its outer end.

In testimony whereof, I afiix my signature.
